Climate change is a change in the world's climate.· Global warming is an increase in the average temperature of the earth's atmosphere.…read more

Slide 3

Greenhouse Effect Energy from the Sun warms the surface of the Earth. A small percentage of this energy is reflected back but at a longer wavelength than the original energy. The outgoing wavelength is prevented from escaping the ENERGY atmosphere by carbon dioxide, water vapour and other gases. These things reflect it backHumans have increased the greenhouse towards the Earth's surface. This iseffect, not produced it. The excess carbon the greenhouse effect, making thedioxide, methane, nitrogen oxides and other temperature inside thegases have contributed to this. This means atmosphere higher than thatthat less long-wavelength energy can be outside.radiated into space, away from the Earth.…read more

Slide 4

Industrial Revolution· During the Industrial Revolution there was a switch from using sustainable resources (charcoal, wood) to using non-renewable resources like coal and later oil. The burning of fossil fuels and deforestation increased the amount of carbon dioxide in the atmosphere from 280ppm to 400ppm.…read more

Slide 5

Methane· Methane concentration has also risen due to the increase in production of rice. Paddy fields (where rice is cultivated) release methane due to the bacteria living in the swampy, anaerobic conditions.· More people means more food meaning more cattle for meat. Cattle rely on gut bacteria to break down cellulose and plant material. A waste product of this is methane (cow digestion can produce up to 40dm^3 of methane per day).…read more

Slide 6

Rice cultivation requires land. To get land, deforestation must occur. This would reduce the diversity of the area because removing trees lessens the food source, shelter and breeding ground of many organisms.· This can cause local extinction because the loss of one organism may result in further losses due to losses in the food chain.…read more
